Also.... my middle-mouse is set to spam left-mouse every 0.2 seconds which is perfect for semi-auto sniper rifles. It will rapid fire them at the exact rate they return to dead center. I have another one set for 0.05 seconds for my 2x burst fire rifles and 3x burst fire pistols making them full auto. It also makes the AI Mana Turret to never have bullet spread. So you can pretty much snipe with it too!
